The Research On Application System Of The Smartphone Based On Embedded Linux

The thesis studies the problems needed to be solved at present concerning how to develop the smartphone application system. According to the problems, the thesis constructs the application development environment of Linux+MiniGUI+C and brings forward a resolution concerning how to develop the smartphone application system, which can solve the above mentioned problem to some extent.The thesis firstly analyzes and compares the functions and performances of the current four kinds of the mainstream smartphone operating system and graphic user interface, and on this basis the thesis achieves to construct the prototype development environment of the smartphone application system. Then, the thesis puts forward a resolution to the smartphone application system, and establishes the use case model, static model and dynamic model of the application system using UML(Unified Modeling Language).As these models are object-oriented and C language is process-oriented, the thesis proposes a method to simulate the object-oriented method with C language. Finally, the thesis implements the primary functions of the communication management, short information management, data communication and game, and testifies the validity of the development environment of Linux+MiniGUI+C.The researches indicate that adopting the resolution can preferably develop the smartphone application system and provides new ideas and techniques regarding the research of the smartphone application system. In addition, simulating the object-oriented method with C language can eliminate the global variables of C language programs and improve the readability, maintainability and portability.of the programs. Simulating the object-oriented method with C language can not only be used to develop the smartphone application system ,but also be used in development in other aspects.
